Find the best tools for your workflow from our broad menu of resins and formats for the purification of recombinant proteins and antibodies. Create a customized purification solution by covalent attachment of a ligand to one of our activated supports. Alternatively, choose one of our easy-to-use and efficient agarose- or magnetic bead–based kits for immunoprecipitation (IP) and co-IP applications. In addition, we’ve developed a range of accessory products for all aspects of purification, including disposable columns and binding and elution buffers.

Broad product selection—affinity supports for the purification and enrichment of antibodies, recombinant proteins, and biotinylated proteins, as well as activated supports for custom protein immobilization

Featured protein purification categories

We offer multiple formats and packs sizes of Protein A, G, A/G, and Protein L immobilized resins that have specific affinity to immunoglobulins, allowing purification of all antibodies of a particular target class regardless of antigen specificity.

We offer a broad range affinity purification products designed for the purification of recombinant proteins—specifically cobalt and nickel IMAC resins for His-tagged proteins and immobilized glutathione resins for GST-tagged proteins. Small-scale resins are also available for c-myc and HA-tagged proteins.

We offer kits in a range of formats for various immunoprecipitation (IP) and co-immunoprecipitation (co-IP) strategies, as well as products for capturing protein-nucleic acid interactions (ChIP and RIP) and solutions for enriching recombinant or modified proteins (pull-down assays).

The strong association between avidin and biotin has been successfully employed in various affinity purification schemes. We offer a variety of immobilized biotin binding supports, including avidin, streptavidin, NeutrAvidin®, CaptAvidin®, and monomeric avidin resins.

Magnetic beads are optimized for protein enrichment from small volume samples with low protein concentrations, such as immunoprecipitation (IP), co-IP, and pull-down assays. Magnetic beads are ideal for assay automation, and are recommended for small-scale and/or screening applications.

We’ve developed activated supports for the immobilization of proteins and other molecules for target-specific affinity purification. The functional groups on the resins utilize a range of coupling mechanism for immobilizing amine-, sulfhydryl-, carbonyl-, and carboxyl-based targets.
